LockNLube Pressure Return Valve (PRV) for Cordless Grease Guns – (LNL81300-M-ANZ / LNL81300-D-ANZ / LNL81300-MK-ANZ) - Applications
An innovative Pressure Return Valve attachment for cordless grease guns that relieves built-up pressure in the grease hose with a twist of a knob.
- Purpose
- Designed for use with high‑performance cordless grease guns
- Prevents dangerous pressure buildup in grease hoses
- Problem Addressed
- Battery‑powered grease guns (e.g., Milwaukee M18) can generate over 10,000 PSI rapidly
- Clogged or blocked Zerk fittings can cause pressure to build before grease flow is noticed
- Excess pressure can lock the coupler onto the fitting, risking sudden grease release or equipment damage
- How the PRV Works
- Twisting the PRV knob opens a valve that routes pressurized grease back into the cartridge
- Instantly reduces hose pressure to zero
- Allows safe, effortless coupler removal
- Eliminates grease spray and waste
- Key Benefits
- Improves operator safety
- Prevents pressure‑locked couplers
- Extends coupler and hose service life by reducing high‑pressure strain
- Speeds up maintenance by eliminating downtime caused by stuck fittings
- Typical Use Cases
- Heavy equipment maintenance (excavators, loaders, agricultural machinery)
- Fleet maintenance for trucks and buses
- Any lubrication work using cordless grease guns for speed and efficiency
- Installation
- Installs inline between the grease gun outlet and the hose
- Remains in place during normal operation
- Activated only when pressure relief is needed
- Model Compatibility
- LNL81300‑M: Fits Milwaukee M12™ and M18™ grease guns; also compatible with Ryobi 18V
- LNL81300-D-ANZ: For DeWalt 20V grease guns
- LNL81300-MK-ANZ: For Makita® 18V LXT®
